Answer: 27
Step-by-step explanation:
The perimeter is the lengths of all sides of the figure added together. Since all sides are equal in this triangle, we know all sides have a length of 9. We know this because all sides have 2 little lines on them, symbolizing that they are equal.
P=9+9+9=27

Answer:
c $99,400
Step-by-step explanation:
$195,00-$120,000=$75,000
$75,000+$5,000+$1,400=81,400
$81,400+$38,000-$20,000=$99,400
Answer:
f(x) = (x - (-5))^2 + (-18)
Step-by-step explanation:
Given:
f(x) = x^2 + 10x + 7
Rewrite f(x) in vertex form
Solution:
f(x) = ax^2 + bx + c is a quadratic function.
The vertex form of f(x) is a(x - h)^2 + k, where (h, k) is the vertex.
=> f(x) = x^2 + 10x + 7
= x^2 + 10x + 25 - 18
= (x + 5)^ - 18
= (x - (-5))^2 + (-18)
=> f(x) can be rewritten in form of a(x - h)^2 + k, where (h, k) is the vertex, with a = 1, h = -5, k = -18
So,
Here we have the following algebraic expression:
The first term of this expression is -5x.
This term is clearly a variable term. The variable is x and its coefficient is -5.
